Just as Mayor Nutter is campaigning to freeze Philadelphia's expensive guaranteed police-fire-public worker pension plan and replace it with a no-guarantees savings-investment plan, a study led by Joshua Rauh at Northwestern University rates Philadelphia's plan as the least-solvent of 77 big-city pension plans, and says it could run out of cash by 2015. Summary and link to report here. Bloomberg story here.
Survey doesn't include Pittsburgh's plan, which was in even worse shape than Philly's, last we checked...
UPDATE: Rauh tells me the 2015 drop-dead date isn't guaranteed. It could happen that fast, IF U.S. investment markets flatten. Or IF city drastically cut pension "contribution" subsidies, which isn't in anybody's budget plan.
But even if the fund meets the city's targets, Rauh says the fund will still run down "in a few more years"; he thinks current city employees "need to be told" their payments are funding today's retiree checks, not setting aside money for their own.
